於week08

 week08

下載老師給的範例

到老師的網頁 https://jsyeh.org/3dcg10/ 下載 win32 和data

解壓縮win32 和 data

將data放入window

打開 Transformation.exe

v ==> vertex  頂點

vt ==> glTexCoord2f(tx, ty)  貼圖座標

vn ==> vertex normal  法向量

f ==> facet  面

開啟MAYA

匯出OBJ檔

把data中的f-16拉出來

將自己做的檔案拉進去並改名成f-16

(裡面的程式碼也要改成f-16)

week08-1

複製上禮拜的程式

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week08");

    glutDisplayFunc(display);

    glutMainLoop();

}

week08-2

把source.zip裡的glm.h放在同目錄

#include <GL/glut.h>

#include "glm.h"

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week08");

    glutDisplayFunc(display);

    glutMainLoop();

}

week08-3

把f-16(自己做的)拉進freeglut的bin(.mtl跟.obj)

按右鍵add file 

#include <GL/glut.h>

#include "glm.h"

GLMmodel * pmodel =NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("f-16.obj");

        glmUnitize(pmodel);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

    ///glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week08");

    glutDisplayFunc(display);

    glutMainLoop();

}

顏色出來

week08-4

*把顏色套進鋼彈模型

#include <opencv/highgui.h> 

#include <opencv/cv.h>

#include <GL/glut.h>

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename);

    cvCvtColor(img,img, CV_BGR2RGB); 

    glEnable(GL_TEXTURE_2D); 

    GLuint id; 

    glGenTextures(1, &id); 

    glBindTexture(GL_TEXTURE_2D, id); 

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); 

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); 

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); 

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

}

#include <GL/glut.h>

#include "glm.h"

GLMmodel * pmodel =NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("Gundam.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel, 90);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL | GLM_TEXTURE);

    ///glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week08");

    myTexture("Diffuse.jpg");

    glutDisplayFunc(display);

    glutMainLoop();

}

千辛萬苦終於成功

轉圈圈

如何github

1. 開啟 Git Bash

2. cd desktop 進入桌面
    git clone https://github.com/jsyeh/2021cce2 把雲端複製下來
    cd 2021cce2 進入你的目錄

3. 把你的 桌面\2021cce2 裡面, 放好你本週的程式 ex. week06 裡面有今天的程式

4. 先把你放好的程式,加入 git 的帳冊
git status (看到紅紅的檔案)

git add .

git status (看到綠綠的檔案)

5. 你要 commit 它
git config --global user.email jsyeh@mail.mcu.edu.tw
git config --global user.name jsyeh

git commit -m "add week06" 

6. git push 推送上雲端
